❔ Can I/How would I do these things with CefGlue.Avalonia?

So im trying to make something, but idk what to do because im not sure how much of this can even be done with CefGlue let alone how i would even start

Basically, im trying to do these things:
- Modify request headers
- Be able to run code when a hyperlink gets clicked before its page gets loaded
- Be able to inject js/css/html
